Why cucumbers in the greenhouse do not grow and what to do?

If it became obvious that the greenhouse cucumbers do not receive due development, it is necessary to take emergency measures until the situation has emerged due to control. In order to draw up a plan for rescue activities, it is important to establish the cause of a negative phenomenon.

No wonder cucumbers are considered a whimsical culture, because the absence of an expected crop can cause a number of agrotechnical errors. These difficulties lead to the fact that many lovers are completely refused to breed this culture. However, the purposeful owners of private sites are methodically comprehended by the technology of growing greenhouse cucumbers, achieving the most optimistic results.

Bad composition of soil

The fertile composition of the soil is dried over time, which becomes the main reason why the cucumbers in the greenhouse do not grow. The main thing is that for this you need to do – systematically replenish the composition of the soil with special additives. Complete update of the soil composition produce every 3 years. To do this, it is necessary to remove the upper layer to a depth of about 25 cm, replacing it with a fresh composition enriched with humus, sand and peat.

It also happens that after flowering, young fruits have been successfully tied up, but instead of the expected development, they suddenly begin to dry out and fall. This suggests that plants need periodic feeding, especially if you have to deal with lowland soil. At the same time, the first feeder produces directly at the time of the seedlings landing.

To do this, diluted with earth or peat.

Unsuitable conditions

If the landing is made too tight, the plants have to withstand a competitive struggle, which significantly reduces the pace of their development. As a result, they not only grow slowly, but sometimes they completely disappear. On the quantitative crop indicator can negatively affect insufficient ventilation or weak illumination. These reasons are eliminated by the regulated nature of the landing, when 20 cm are maintained between the sprouts, and 60 cm is left for inter-row space.

Another important condition for the full development of culture is considered temperature control. The optimal difference between the day and night air temperature should be +25 and +15 degrees, respectively. If the temperature becomes lowering below the mark of +15 degrees, the plants will suffer from slow growth and bad formation of zones. In addition, fruits can take distorted (curved). If the temperature exceeds the limit of +30 degrees, the process of fertilization will be disturbed, and the wound will stop forming.

Lack of fertilizers

The disadvantage of fertilizers can cause the seedlings dies, and the planted plants drooped and do not develop. If this did not happen, and all the sprouts after the landing began to be well, stop the feeder should not be heard. Sometimes even successfully accepted cucumbers die.

Periodic alternation of varieties of injunified elements is considered the most effective system of feeding. The main emphasis is placed on a nitrogen ratio with phosphorus.

It should be known that the excess of the nominated component leads to the active development of the tops, and the plant does not have forces for full fruiting. The leaves acquire a bright green color and differ in their magnitude. But the activity of the formation of the strings is noticeably declining, most of the flowers blooms invested.

The high content of nitrogen is accompanied by a lack of phosphorus, as well as potassium, which is necessary for the plant for the formation and development of fruits. At each stage of development, the plant needs a certain composition of feeding, depending on the current growth phase.

Root

For feeding the roots use either dry mixes or liquid substances. Dry mineral formulations need to be made in the soil during the mass treatment period – after winter frosts leave, as well as at the time of landing, adding a small amount into each well. Liquid solutions are much more efficient to use in the period of active development of the plant, due to the ability to quickly digest. When making feeding, it is necessary to rely on the instructions and advice of gardeners on a specific drug.

Extrannevy

Extra-corner feeders make it possible to maintain the vitality of the plant during periods of transition to the next phase of development. They are produced at the stage of active growth, at the time of flowering, as well as at the stage of fruiting. This amplification means allows to increase both growth efficiency and the ability of the formation and development of fruits. Irrigation is performed at 100 ml of active composition per 1 m2.

Salt stains, which as a result can settle on foliage, should be carefully removed.

Treatment of disease

Various diseases may cause serious difficulties in the development of cucumbers, the cause of the disease fungi. The fungus lives and develops in the soil, where does the plant come from. The uncontrolled development of fungal organisms leads to the destruction of culture.

ClapPorios

So that the plants are not affected by this disease, it is recommended to take measures to prevent the spread of the pathogen. For this purpose, some recommendations should be followed:

  • provide systematic ventilation of the greenhouse;

  • Do not leave the remains of plant mass on the beds;

  • Do not use cold water and sprinkling technique.

With the appearance of the first signs of the disease, it is necessary to suspend by watering for a period of 5 days. In this period, plants are treated with one-percent composition of the burgue mixture or copper chlorokising with 0.4% content.

Root rot

To prevent the development of root rot, it is necessary to create the following conditions:

  • comply with the regulated distance between the crops;

  • in time removed from the soil the remains of the plant mass;

  • eliminate cold water.

At the first signs of the occurrence of the disease, it is necessary to take measures to stimulate the development of new root processes. For this purpose, a fertile soil in a depth of 5 cm is added to each plant. This will allow cucumbers to root again.

Puffy dew

You can prevent the development of this disease by taking the following measures:

  • timely to collect fruits and plant balances;

  • disinfect the greenhouse after harvesting, using a solution of formalin;

  • to keep the air temperature within 25 degrees;

  • providing watering with warm water;

  • Use hybrids resistant to mildew.

In the first signs of the occurrence of the disease, it is necessary to treat plants with a solution of chlorocycy copper. For its preparation use 40 g of a concentrated mixture divorced by 10 liters of water. And you can also use a colloidal sulfur, it is also bred 40 g in 10 liters of water.

Fighting pests

Various insecticides help to organize the fight against pests. For their absence, you can use the practice of using folk remedies.

For this purpose, a soap solution may be suitable, a decoction of a lowful husk or welding of garlic arrows.

White white bottle

The first measure of protection against this pest is a mosquito net that needs to be installed on the vehicles and doorways. In addition, it is necessary to monitor the lack of weeds in the soil.

If the insect was noticed, you should resort to traps. For this purpose, a piece of plywood white paint is painted, and after drying, lubricated with a vaseline (can be castor oil). As an additional preventive measure, it is possible to periodically wash the leaves of cucumbers from the bottom, where the whiteflink barrier strives to arrange its masonry.

Bahch wane

This variety of pests extends mainly with weeds. This means that the first measure of salvation will be their absence on the beds. As an active agent to counteract the TEL, welding of tobacco and bitter pepper are used. In this case, 200 g of tobacco is mixed with 30 g of chopped pepper pods, poured with a hot soap solution (10 l) and the day insist. And you can also use another mixture, when 2 glasses of ash poured 10 liters of hot soap solution. This composition also needs to insist.

Prevention measures

To avoid damage to the root system when disembarking seedlings, you can land the seeds for pre-prepared beds. And also for seedlings often use individual dishes, from which the plant is transplanted together with the Earth.

It is necessary to remember the additional feeding of plants during the appearance of the uncess, which intensively need nutrients. Fruit collection is better produced in the morning or in the evening. On time, not cleaned fruits will overper and prevent the development of new formations.

The excess amount of vegetative mass also prevents the development of fruits, redirecting nutrients for its own content. Extra leaves are removed, which also reduces the degree of dimness, which represents a threat to young bandages.
